About Add Prefix and Suffix
A string is added to the start or end of every line. The everyday uses are mechanical and constant: turning a column of values into a quoted SQL `IN` list, wrapping paths in quotes for a shell command, adding a comment marker to a block of code, or building repetitive config from a plain list.
How to use it
- Paste the text you want to run through add prefix and suffix.
- Set prefix, suffix and skip empty lines.

Questions
Are empty lines given a prefix too?
No, blank lines are skipped, which is what you want when commenting out a block of code with gaps in it.
Can I add a comma to every line except the last?
Not directly. Add the comma to every line, then delete the final one, or use the SQL IN Clause Builder, which handles the separator properly.
